How To Use

ChaiBatchConvertor

Step 0, Installation

nebula-chia could be installed either via pip or from this git repo itself.

Install via pip

python3 -m pip install nebula-chia

Install from the github repo

git clone git@github.com:wey-gu/nebula-chia.git
cd nebula-chia
python3 setup.py install

Note:

Nebula-chia depends on chia-blockchain, the easiest way is to call it from the venv inside the Chia Network repo.

• Install Chia Netowrk refers to https://github.com/Chia-Network/chia-blockchain/wiki/INSTALL

• Activate venv like:

• cd chia-blockchain
  . ./activate

Step 1, Convert Chia as CSV files

ChiaBatchConvertor is used to convert Chia Block Chain data into CSV files, which could then be used for nebula-importer

$ python3 -m pip install nebula-chia
$ python

# block_record_limit = 0 means unlimited
# coin_record_limit = 0 means unlimited
from nebulachia.convertor import ChiaBatchConvertor
c = ChaiBatchConvertor(block_record_limit=0, coin_record_limit=0, write_batch_size=10000)
c.convert_block_record()
c.convert_coin_record()
exit()

$ ls -lth

-rw-r--r--   1 weyl  staff   173M May 19 13:01 coin_record.csv
-rw-r--r--   1 weyl  staff    77M May 19 12:59 block_record.csv
...

Step2, Import CSV files to Nebula Graph

In above steps, we already have coin_record.csv and block_record.csv generated, now we could import the data into a nebula graph cluster with the help of Nebula-Importer.

The nebula-chia.yaml in this repo is the config file for nebula-importer.

❯ tree nebula-importer
nebula-importer
└── nebula-chia.yaml

Below is an example of running importer, which assumed both our CSV files and the nebula-chia.yaml placed in path /home/nebula/chia/.

docker run --rm -ti \
    --network=nebula-docker-compose_nebula-net \
    -v /home/nebula/chia:/root \
    vesoft/nebula-importer:v2 \
    --config /root/nebula-chia.yaml
